if I am right Top Gun has been racing in Titles more recently than your new Mossie, never under estimate the advances made in sails and rig set ups in recent years by the Mossies, as you have been known to say, despite the rumours Mossies are not dead and development has seen them progress well in the southern states
Have a good look at the way Top Gun is set up and work towards that, perhaps one thing that is most difficult to set up is centreboard positions this is worth checking as it will effect the amount of rake in the mast you can use. If twitchyness is a problem also check rudder alignment and rake of rudders.
You mentioned in earlier post the Brass Monkey regatta, do you mean the one from the Flying Squadron? and when is it on?
